Phthalocyanines and related compounds: XLIV. Synthesis of conjugates of phthalocyanines with rhodamines
摘要:
A series of conjugates of sulfo- and carboxy-substituted phthalocyanines with rhodamines were prepared, and their electronic absorption and luminescence spectra were studied. An intramolecular transfer of the excitation energy from the rhodamine moiety (donor) to the phthalocyanine moiety (acceptor) was revealed.
Synthesis of probes with broad pH range fluorescence
摘要:
Reaction of a rhodamine 2'-ester with an excess of alkyldiamines provides amino-functionalized rhodamine spirolactams, which when subsequently conjugated with carboxyfluorescein, provides probes which are fluorescent at acidic, neutral, and basic pH ranges.
